You can look at Clean Food by Terry Walters and also check out Gena Hamshaw, she is a regular contributor here on food52 has amazing vegan/raw recipes here is a link to her website http://www.choosingraw... and also check out in features here on food52 The New Veganism.

Coincidentally, these books are mostly vegetarian oriented (Sprouted Kitchen has a few meat-based recipes, but not many), but it would be wise to point out that a vegetarian diet (nor a vegan one) is innately healthy. It's all about balance.

I know that they have been mentioned already but Heidi Swanson's (Super Natural Cooking; Super Natural Everyday) and Terry Walter's (Clean Food; Clean Start) books are EXCELLENT!! Cooking from their books really helped me get on track when I needed to eat a little healthier but still wanted great food.

Any of the above recommendations in this nutritionist's opinion would be excellent choices. Kudos to you for linking healthy with cooking, which may be the single most important component of healthy eating.
